Fixed Rate full term??

Hi im trying to sort my finances out i have a house worth 80000 and owe 54000 on it so im looking for a good fixed rate deal on my mortgage im toying with the idea of fixing the rate for the remainder of the term which will be 15 years because the interest rate will inevitably go back up again at some point right, would now be the best time to fix it as it cant go lower just higher??

Any advice would be appreciated thanks............oh and im sticking to 15 years so i can be mortgage free by 43 :rotfl:
